Abstract: A pool dome for covering an outdoor swimming pool during the fall and winter seasons comprising vertical structural walls and a plurality of inflatable sections formed between the walls. The vertical structural walls provide sufficient structural support for the inflatable sections capable of holding its dome shape even during heavy wind, rain, and snow conditions. The swimming pool dome is sized and shaped to cover the entire water surface of the swimming pool and lies between the pool water and the cover for raising the cover in a dome shape to prevent rain water, snow, ice, and other unwanted debris from collecting on top of the pool cover.
